METAL FRAME FOB WINDOW SCREENS.

Application filed December as, 1925. Serial 1T0.- 1 s,ao4 f My invention relates to hollow-sheet metal frames for holding screens, posters or p1c tures, or for any other purpose for whlch a small strong frame is required. It is an I especial object of my invention to provide a metal frame screen that will frictionally hold screen wire in its roughened depressions, making it simple and practical to wire the frame without t e wire slipping out un- 10 til a hard cord of any suitable kind can be pressed into the center of the fold of the novel foundation angle members or cornerpieces of di-fi'erent lengths each way and which may be cut to approximately match 20 the size of the frame desired; and to assemble the metal screen frame in a facile and eflicient manner.

I attain these-and other objects of my in- 'vention by the device illustrated in the ac- 25 companying drawings, in which Flgure 1 is a front planview of my inventlon;

Fig. 2 is a section on line 2--2 of Fi 1; Fi 3 is a perspective group view the mem rs forming the foundation angle or corner piece with portions of the longitudinal frame members that engage in said cornerpi'ece; and

Fig. 4 is a detail view showing the method of mounting the spring 13 in frame 1.

Like characters of reference designate like parts in each of the several views.

Referring to the accom anying drawings, I provide longitudinal an transverse frame members 1 having longitudinal depressions 2. I also provide inner foundation angle frame members or corner pieces 5, from whichthe frame members 1 telescope, as indicated in dotted lines at one of 45 the corners of Fig. -1.- Frame members 1 are provided with a beveled or mitered end 17 so as to meet diagonally at the -corners. Frame members 1 are provided with approximately U-shaped recesses 3 and these recesses have opposite roughened surfaces 4 to frictionally engage the wire screen mesh 6, which is held in place by a suitable hard .lengths and out up to the desired length an...

cord 7 as shown in Fig. 2.- I provide a plate 8 approximately L-shaped in cross section to engage the screen frame 1 and screen 6 and to conceal the cord 7. as illustrated in Fig. 2. Plate 8 is fastened to frame 1 in any suitable manner, preferably by 'hollow rivets or bolts, such as the members 19 and 20, shown in Fig. 2. Plate 8 is provided with a longitudinal depression'9 positioned opposite the corresponding longitudinal depres- V sion 2 of frame 1. Plate 8 is provided with a beveled edge 18 adapted to be engaged by the correspondingly flan ed ed e 10 of screen frame 1, as illustrated 1n section in Fig. 2. I provide an outer corner piece or. angle cover 11 having depressions. 12 corresponding in position and size with the depressions 2 and 9 of frame 1 and plate 8. The whole frame is 'held together by suitable rivets or double screws after the wire screen, has been put in.

To permit of convenient insertion and removal of the screen, I provide springs 13 75 both mounted on one side of the screen frame, as shown in Fig. 1, the screen frame having a handle 15 attached to the opposite side thereof and having suitable handles 16 Y on the bottom portion of the screen. The spring 13 is mounted in apertures 14 in frame members 1. 5 7

' The frame members may be made in long assembled wherever desired. The corner pieces 5 constitute the foundation elements' over which the frame members 1 are telescoped, the beveled or 'mitered edges 17 forming a tight and concealed joint. The outer corner'piece 11 engages over the corners or angles of the screen frame. The wire screen mesh is readily fastened to the metal frame by inserting it in the U-shaped recess 3 and pressing a hard cord or any' other suitable longitudinally extendin fasand conceals cord 7 is suitably fastened to faces of the the frame 1 by any suitable means but preferably by hollow rivets or bolts.

It is within the contemplation of my invention to provide metal rollers at the bottom for horizontally rolling the screens.

An important feature of my invention is the provision of the separate inside angle pieces, as this construction permits of the screen being built in various parts of the country and the framemembers, which are stamped out in long lengths, cut to the proper length and fitted in'the corner pieces in the manner illustrated in the drawings. This improvement is of importance, inasmuch as during the summer season the time lostin making special frames, finishing them and shipping them to distant points is one of the most expensive features of thescreen industry.

It is within the contemplation of my invention to alter the angle of the corner piece from a rightangle should a modification of shape be esirable for special purposes. It is also within the contemplation of'my, invention to make'the frame of any suitable metal 'or other material which may be pressed or stamped to the desired shape. It is also an im rtant feature of my invention to rovi e the roughened sur- -shaped recess to permit of readily securin the wire mesh screen to the frames and olding it in place by means of a hard or waterproof cord, which cord can be concealed by the plate 8 which is u fastened to the main frame members.

My screen frame is normall about three hths of an inch thick by t ree quarters an inch wide whenfinished, but may be made smaller when using copper, bronze,

zinc or aluminum for the outside tubular shell. It is within the contemplation of'my tune in the frame, as illustrated in invention to modify the shape of the corrugations or grooves without essentially departin from'the angle construction hereinabove escribed. The yielding springs 13 are loosely mounted in the frames 1 but are prevented from losing out by reason of the hook-shaped ends which engage in the a r- 4 of the drawings The handles may be v to make these frames fit and operate prop- 'erl 'on various kinds of wood and metal sasli windows, and for other uses, such as poster or picture frames.

What I claim is 1. In" metal frames of the class described, 7

the combination of hollow metal outer frames, inner angle frames snugly fitting in the outer frames, the outer frames having longitudinal depressions to frictionally engage the angle frames, the outer frames havlng an approximately U-shaped recessed portion extending longitudinally of the frame and adapted to receive a portion of the wire screens, screen-securing elements seatable in the recessed ally hold the wire screen 1n place, metal strips en a'geable over the screen securing elements and wire screen, said strips'having a longitudinal depression to frictionally enga e the wire screen, the outer metal corners o suitable size to and frictionally engageableover the corners of the frames, and springs attached to one side of the metal frames to resiliently and frictionally hold the screens in place in channel guides on the windows. 2. In metal frames of the class described, the combination of chollow metal outer frames, inner angle frames snugly fitting in the outer frames, the outer frames havingv longitudinal depressions to frictionally engage the angle frames, the outer frames having an approximately U-shaped recessed ortion extending longitudinally of the rame and adapted to receive a portion of the wire screens, screen securing elements seatable in the'recessed portions to frictionally hold the wire screen in place, metal strips engageable over the screen securing elements and, wire screen, said strips having longitudinal depressions to frictionally engage the wire screen, hollow metal corners of suitable size to and frictionally engageable over the corners of the frames.
